This document specifies a test method and the minimum requirements for bactericidal activity of chemical disinfectant products intended to be used for treatment in aqueous systems against Legionella pneumophila that form a homogeneous, physically stable preparation when diluted with buffered ferrous hard water or hard water. Whenever Legionella pneumophila poses a risk to human health, this method is suitable for water used in cooling towers and water for general purposes, like spas, pools, showers and other uses. The method is not suitable for electro-chemical disinfection.

The European Standard applies to products used as a single application shock treatment in order to kill Legionella pneumophila. It is not suitable for the evaluation of those products that are dosed continuously in to water systems to control the growth of Legionella pneumophila.

NOTE 1 The method described is intended to determine the activity of commercial formulations or active substances under the conditions in which they are used.

NOTE 2 This method corresponds to a phase 2 step 1 test.

NOTE 3 This method does not take into account the fact that Legionella pneumophila is often found in cells of amoebae and/or biofilms and that thereby a product’s activity against the bacteria may be reduced.

EN 14885 specifies in detail the relationship of the various tests to one another and to "use recommendation".

This document specifies the validation protocol of analytical methods used for ensuring the quality of the gaseous hydrogen quality at hydrogen distribution bases and hydrogen fueling stations for PEM fuel cells for road vehicles. Recommendation on calculation of uncertainty budget is also given in this document.

This protocol is established mainly for analysis done in laboratories after the sampling of hydrogen either at hydrogen distribution bases or at hydrogen refueling stations. The specific requirements for on-line monitoring are not covered by this document.

A list of suitable analytical techniques used to measure each impurity in hydrogen, according to the specification defined by ISO 14687, is also given in this standard.

Moreover, recommendations for keeping the integrity of the sample are also given in order to ensure the quality of the measurement.

Guideline for reporting the analytical results is also included in this standard.

This European Standard specifies a test method and the minimum requirements for bactericidal activity of chemical disinfectant and antiseptic products that form a homogeneous, physically stable preparation when diluted with hard water or - in the case of ready-to-use products - with water. Products can only be tested at a concentration of 80 % or less, as some dilution is always produced by adding the test organisms and interfering substance.

This document applies to products that are used in food, industrial, domestic and institutional areas excluding areas and situations where disinfection is medically indicated and excluding products used on living tissues except those for hand hygiene in the above considered areas. The following areas are at least included:

a) processing, distribution and retailing of:

1) food of animal origin:

— milk and milk products;

— meat and meat products;

— fish, seafood, and related products;

— eggs and egg products;

— animal feeds;

— etc.

2) food of vegetable origin:

— beverages;

— fruits, vegetables and derivatives (including sugar, distillery, etc.);

— flour, milling and baking;

— animal feeds;

— etc.

b) institutional and domestic areas:

— catering establishments;

— public areas;

— public transports;

— schools;

— nurseries;

— shops;

— sports rooms;

— waste containers (bins, etc.);

— hotels;

— dwellings;

— clinically non sensitive areas of hospitals;

— offices;

— etc.

c) other industrial areas:

— packaging material;

— biotechnology (yeast, proteins, enzymes, etc.);

— pharmaceutical;

— cosmetics and toiletries;

— textiles;

— space industry, computer industry;

— etc.

EN 14885 specifies in detail the relationship of the various tests to one another and to "use recommendations".

NOTE 1 The method described is intended to determine the activity of commercial formulations or active substances under the conditions in which they are used.

NOTE 2 This method corresponds to a phase 2 step 1 test.
